民用建筑的混凝土圈梁断面一般不大,但耗用木材较多,且费工费时。若采用钢模板、钢管夹条,槽钢穿墙挡和钢筋斜撑施工可避免上述弊病,缩短工期。 1.材料准备 (1)钢模板:采用成品钢模板,长度方向可用回形销拼装。 (2)钢管夹条:利用现场搭设脚手架的钢管,长度根据实际需要用接头扣件联接。 (3)槽钢:用8～10号槽钢,一侧焊有角钢,用另一侧钻孔作安装活动木块用,距两端8cm处各钻一个孔作固定短木块用。
The concrete ring section of a civil building is generally not large, but it consumes more wood and is time-consuming. If the use of steel templates, steel pipe clips, channel steel wall block and steel bracing construction can avoid the above shortcomings, shorten the construction period. 1. Material preparation (1) Steel formwork: The finished steel formwork is used, and the length direction can be assembled with clip-on pins. (2) Steel pipe clamps: The use of on-site scaffolding steel pipe, the length according to the actual need to use connector fasteners to connect. (3) Channel: Use 8 to 10 channel steel, one side welded with angle steel, the other side of the hole for the installation of wooden blocks, drilled one hole from each end 8cm for fixed short blocks.
